This is application is a continuation of U.S. provisional application Ser. No. 60/490,152 filed Jul. 25, 2003 and U.S. provisional application Ser. No. 60/490,227 filed Jul. 25, 2003.
The present invention relates generally to a stir stick and more particularly to a stir stick adapted for use with a blender apparatus.
Blenders, smoothie makers and beverage mixers have become increasingly popular for making frosty drinks, such as milkshakes or smoothies. Milkshakes are typically made of ice cream and/or milk, and flavored as desired, with or without additives, such as candies, chocolates, peanut butter, flavored syrups, etc. Smoothies are typically healthier than milkshakes and are made with ice, frozen yogurt or sorbet, and fruit juice, and can include additives such as fruit, vitamins or supplements. Milkshakes, smoothies and other frosty drinks are hereinafter collectively referred to as “frozen beverages.”
Restaurants and specialty food stores prepare frozen beverages using commercial quality blenders. When consumers attempt to replicate the frozen beverage recipes at home, they typically find their standard kitchen blender to be inadequate for the task. A disadvantage of the known kitchen blenders is that the blender gets clogged or otherwise stalled by the drink ingredients. Another disadvantage is that the ingredients are not sufficiently circulated through the blades so that large pieces of ice, fruit or other ingredients remain even after the beverage is fully mixed.
To ensure proper chopping and mixing of the ingredients, it is often necessary to supplement the blending by stirring the ingredients with a spoon or spatula. If the-blender is in operation when stirring the ingredients with a spoon or spatula, there is a danger of hitting the mixing blades with the spoon or spatula and this could result in contamination of the food, damage to the blender or injury to the person holding the spoon or spatula. Also, material pushed into the blades when the lid is not on the blender container is likely to be thrown upward out of the container by the rapidly rotating blades which will make a mess of walls, cabinets or counter space in the vicinity of the blender.
To avoid the danger and mess created by stirring the ingredient while the blender is in operation, the user must interrupt the blending process by turning the blender off, removing the lid and then stirring the ingredients. The disadvantage of this process is that it inconveniently lengthens the preparation time and adds numerous additional steps to the preparation process.
Thus, it is desirous to provide a stir stick for a blender apparatus that enables the user to stir the ingredients without presenting a danger to the user or creating a mess.
A stir stick assembly is disclosed having a stir stick body with a control end, and a stirring end opposite the control end. The stir stick body includes a plurality of sections that are detachably mated together. The stir stick body further defines a passageway extending from the control end to the stirring end to facilitate the addition of ingredients to the blender without requiring the user to turn the blender off.
As shown in
In the embodiments shown in
As shown in
In the assembled configuration, the first end 26 of the first section 12 is substantially aligned with the first end 36 of the second section 14; and the second end 28 of the first section 12 is substantially aligned with the second end 38 of the second section 14. In a preferred embodiment of the invention, the first section 12 defines a first concave groove 24 therein and the second section 14 defines a second concave groove 34. In an assembled configuration, the first and second concave grooves 24, 34 form a passageway 40 for liquid or solids to be added to the beverage mix in the blender 100.
To prevent the stir stick assembly 10 from falling through the opening 102 of the blender lid 104, the stir stick assembly 10 is provided with a collar 44 that extends beyond the opening 102. In a preferred embodiment of the invention, the collar 44 is a continuous flange around the periphery of the stir stick assembly 10. However, the collar 44 can be any known structure that prevents the stir stick assembly 10 from falling through opening 102. For example, in one embodiment of the invention, the collar 44 is a plurality of tabs that extend radially from the stir stick assembly.
In a preferred embodiment of the invention, the stir stick assembly 10 is installed in an opening in the center of the blender lid 104. The central position of the stir stick assembly 10 enables the user to be able to stir the frozen beverage from the center of the mixture. Furthermore, the stir stick assembly 10 is preferably positioned such that the outlet 48 of the passageway 40 is positioned directly above the blades 110. The passageway 40 enables the user to add ingredients to the frozen beverage while the blender is in use without the frozen beverage splattering out of the blender. Liquid poured through the inlet 46 of the passageway 40 will exit at the passageway outlet 48, directly above blades 110. The outlet 48 is preferably positioned to facilitate the mixing of the added ingredients with the frozen beverage by delivering the added ingredients to the mixing blades 110 or very close to the mixing blades 110.

As shown in
After each use, the stir stick can be disassembled to facilitate the cleaning of the stir stick. Specifically, as shown in
It is envisioned that any known interlocking members can be used to detachably secure the first and second sections of the stir stick to each other. As such, the invention should not be limited to the specific interlocking members described herein.
Many modifications and other embodiments of the invention set forth herein will come to mind to one skilled in the art to which the invention pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the invention is not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
